ds1TxPRBS

Module: Fore-DS1-MIB

OID (symbolic): Fore-DS1-MIB::ds1TxPRBS

OID (numeric): 1.3.6.1.4.1.326.2.2.1.1.7.1.1.1.18

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable controls the Pseudo-Random Bit Sequence Generator (PRSG) which generates an unframed 2^15-1 test sequence as define in Recommendation O.151. The pattern may be inverted.

What is ds1TxPRBS?

Turns on or off (or inverts) an unframed 2^15-1 pseudo-random bit sequence generator per ITU-T O.151, used to inject a known test pattern onto the DS1 line for bit-error-rate testing. Set to on(2) or invert(3) during circuit turn-up testing, then back to off(1) for normal service.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.7.1.1.1.18
snmpwalk -v2c -c public <target> Fore-DS1-MIB::ds1TxPRBS

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.2.1.1.7.1.1.1.18.1
snmpget -v2c -c public <target> Fore-DS1-MIB::ds1TxPRBS.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.326.2.2.1.1.7.1.1.1.18.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ds1TxPRBS.1
